I do have my doubts about this part.

The Steinberg license _explicitly_ prohibits the reverse-engineering of
the VST-SDK, not only the distribution or selling. Whether it's moot or
not is beyond me, IANAL, but IMHO, I'm afraid the LMMS/DSSI-VST vestige
header won't stand much in case of litigation.
